If you want to find something cheaper, to feel your way back to fountain pen, go to your local Office Depot and find the cheap Yafa fountain pen, in a blister pack, usually next to refillable ballpoints like the Parker Jotter.
Office Depot also has Cross fountain pens.
Staples has my number 2 fountain pen of choice, the Waterman Phileas.
I have multiple of them and I like them a lot. They are also around $24-30 depending on the store.
They may have a sale, right now.
If you want really really cheap starter pens at Yafa fountain pen price, your only other option is an internet seller.
Got to the fountain pen forum at http://www.fountainpennetwork.com/
Sign up and ask a lot of questions about cheap, starter fountain pens in the writing instrument sub forum.
The Lamy Safari and Watermam Phileas are my personal favorites but I know that there are cheaper fountain pens available.
